a line.
A line is a series of points that extends in two opposite directions without end.It has no thickness.

A line?
A line extends in both directions without end. In geometry, a line is defined as a straight one-dimensional figure that has no thickness and extends infinitely in both directions. This concept is fundamental in mathematics and serves as a basic building block for other geometric shapes and concepts.

it is called a line imma 7th grader yall
A plane.
It is a plane
Plane is one of the undefined terms in mathematics which has no thickness or depth but has length and width, it extends without end in all directions.
This is a basic concept in geometry and refers to a point or a dot as having no dimension. Similarly, a line extends in two directions without a direction and a plane extends without an end. On a drawing these things look concrete, but in theoretical terms they remain undefined.
